Object The use of intracranial stents in stent-assisted coil embolization is now a current neurosurgical practice worldwide. clinical utility these the sole stenting (SS) technique, however, has not been thoroughly described, and published reports this experience are scarce. This study was designed to evaluate SS treatment dissecting nondissecting aneurysms posterior circulation. Methods prospective descriptive conducted 20 consecutive patients who harbored single circulation were treated...
So-called direct carotid-cavernous fistulas (CCFs) are commonly treated by detachable balloons or coils to occlude the shunt while sparing carotid artery. Liquid embolic agents have been rarely used, and in particular, authors' knowledge, use of Onyx as sole agent has never reported an indexed publication.The authors describe a case series 5 patients with posttraumatic CCF whom embolization was prospectively used strategy management.Complete occlusion obtained at end procedure 4 cases,...
Abstract OBJECTIVE AND IMPORTANCE: Vertebrobasilar aneurysms have a risk of rupture ranging from 2.5 to 50% (especially those larger than 7 mm) and repeat bleeding rate between 30 70%. For this reason, patients with mm should be treated. Considering the high complexity surgical approaches in area, an increasing number reported cases are being treated endovascular therapy. The purpose article is determine effectiveness safety sole stenting bypass treatment three consecutive vertebrobasilar...
The cumulative experience worldwide indicates complete radiosurgical obliteration rates of brain arteriovenous malformations (AVMs) ranging from 35 to 90%. purpose this study was propose a strategy increase the rate for AVMs through dynamic definition key target volume (KTV).A prospective series patients harboring an AVM assessed using digital subtraction angiography in which counter used measure several stages frame-by-frame circulation time. All were analyzed measurement planning define...
✓ The authors report on the case of a 38-year-old woman who had experienced incapacitating pulsatile tinnitus in left ear for 6 months. Angiographic studies revealed wide-necked venous aneurysm transverse—sigmoid sinus. Solitary stent placement across neck resulted slight modification lesion's characteristics. A second session, which embolization with Guglielmi Detachable Coils was performed, 100% occlusion aneurysm, patency parent vessel and resolution tinnitus.
✓ Vascular complications after percutaneous injection procedures for relief of trigeminal neuralgia are varied, ranging from puncture arterial or venous structures to carotid-cavernous fistulas. The authors present a patient in whom an external carotid artery fistula occurred microcompression procedure the treatment left-sided neuralgia. This is believed be first case this complication secondary facial pain.
We describe the case of a 59-year-old female presenting with disabling pulsatile tinnitus caused by venous aneurysm sigmoid sinus. This is first successful sole stenting, using closed-cell design in central part stent, leading to occlusion and cure tinnitus. Venous aneurysms dural sinuses are rare causes stenting technique provides simpler, safe, effective approach.
Intracranial aneurysms uncommonly present with ischemic stroke. Parent artery occlusion due to local extension of the luminal thrombus, ejecting emboli distal arteries, or increased mass effect have been described as possible pathogenic mechanisms. Guidelines for management these patients are absent. We clinical outcome and radiological characteristics three spontaneous thrombosis intracranial a cause This information is relevant given benign history in terms stroke recurrence risk bleeding.
The outbreak of COVID-19 has created a landslide publications, from different sources and unequal impact. We considered that the first 3 months are crucial to understand how knowledge been generated by performing bibliometric analysis, including citations these articles guide researchers in exploring this field, evaluate relationship between confirmed cases deaths with number papers per country.Scientific publications were obtained PubMed (January-March 2020) their during 6 retrieved Scopus...
✓Endovascular treatment of intracranial aneurysms has evolved since the introduction detachable coils. Sole stenting is a brand-new technique that recently emerged as definitive for saccular or fusiform at particular locations. Superior cerebellar artery are rare, and few treated cases have been reported. Most them surgically, endovascular usually managed with occlusion parent vessel. The authors report on first two endovascularly complete cure aneurysm well preservation vessel distal...
To describe the roadmapping technique and our three-year experience in management of intracranial aneurysms hybrid operating room.We analyzed all patients who underwent surgical clipping for cerebral with from January 2017 to September 2019. We report demographic, clinical, morphological variables, as well clinical radiological outcomes. further three illustrative cases technique.A total 13 were included, 9 which (69.2%) presented subarachnoid hemorrhage, a 23 treated aneurysms. All female,...
Sinus pericranii (SP) is an abnormal communication between the intracranial and extracranial venous drainage pathways. Treatment of this condition has mainly been recommended for aesthetic reasons prevention hemorrhage. The authors report a conservative treatment potentially lethal complications.
The sole stenting technique has emerged as a new tool for the management of intracranial aneurysms. However, several concerns have about long-term behavior stents, particularly their safety and efficacy. We present first case an aneurysm intentionally treated with technique. After ten years clinical imaging follow-up, lesion healed no intrastent stenosis is observed. Several issues concerning this are discussed. For instance, modification angle intra-aneurysmal thrombosis may account...
Summary. Juvenile nasopharyngeal angiofibroma (JNA) is a rare histologically benign tumor, highly vascularized, with usually aggressive behavior, and can extend from the nasal cavity to neighboring structures. We present case of 14-year-old male harboring JNA, presenting an active severe persistent epistaxis. Two previous surgical attempts removal were unsuccessful, because profuse intraoperative bleeding. Angiography showed vascularized neoplasm multiple branches arising both internal...
Persistent primitive trigeminal artery (PPTA), a fetal carotid-basilar anastomosis, is the most common embryological vascular remnant persisting into adult age. However, reported cases associated with cerebral aneurysms are rare. A 33-year-old female presented an extremely rare PPTA-basilar (PPTA-BA) aneurysm manifesting as subarachnoid hemorrhage. Computed tomography revealed bleeding in prepontine cistern, and angiography disclosed PPTA-BA aneurysm. The was managed stent-assisted coiling...
